Application led August 11, 19059. Serial No. 512,429.

To all whom it may concern:

Be it known that I, ALMON E. PnEs'roN, a citizen of the United States, residing at Battle Creek, in the county of Calhoun and State of Michigan, have invented vcertain `new and useful Improvements in Spraying- Nozzles; and I do hereby declare the following to be a full, clear, and description of the invention, 'such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to spraying nozzles and has for its object to so construct an ordinary garden hose nozzle that in addition to its general purpose it can be used as a s rayer for fruit trees and shrubbery and a so for applying a liquid fertilizer to lawns and gardens.

The invention consists in .the novel organiend lclosed, as at 2, except for a series of openin s yor. perorations 3 arranged near the peliiphery thereof. A tubular extension 4 is iixed to the opposite side of the closure plate 2 interiorly of the perforations 3. Said tubular projection 4 is screw-threaded internall-4 and externally and is engaged on its outer ce by a tube 5 while another tube 6, of less diameter than the tube 5, engages its interior screw threads.

Between 'the closure plate 2 of the Vpart 1 .and :the adjacent end of .the tube Y5, and mounted :to turn upon the tubular proj eetion 4 is a ring-valve C( having 4passages 8 formed therein adapted to register with the perforations 3 and also with other perforations 9 in said tubular rojection. It will be understood that ring --may be turned to Vbring the passages 8 .out of alimement with 'the :pertorations .3 and 19, and that the iiow of water from the part luto the interior of the tubular projectlon willkthen be eut off. The periphery of the valse-ring extends beyond the other parts ai the nozzle and is preferably milled whereby it may be con- Veniently asped and turned for controlling the How o water through the nozzle.

The inner tube 6 extends beyond the outer tube 5 andis reduced on its outer surface, as at 1,0, from a point interior- 1y of the .end .of said outertube. The inner surface of the outer tube at the extremity threof, is out away, as at 11, thereby enlar ing the diam-eter of the chamber formed .ti erein and r0- viding a shoulder 12 at the inner en of 'said enlarged portion. An internally sorewthreaded ring 13 is tted in said enlarged portion 11 and abnts against said shoulder 12, Another tube 14 has screw connection with the interior of the ring 13 land is .of such internal diameter as to'leave a passa e between it and the reduced ortion of te inner tube 6, and so as to a so permit the end of said tube 14 -to .contact with the shoulder 15 on said tube 6 at the end of said reduced portion for the purpose .to be hereinafter explained.

The ring 13 is held in place and ,air is excluded from the chamber between the outer v tube 5 and the inner tube 6 by means of a screw-threaded cap 16, a 'washer 17 and suitable packing material 18 all iitted around the .tube 14. Beyond said cap, the

last mentioned .tube is provided wvlth a milled band 19' byaneens of which Said tube may be turned for moving the same inward or outward `to suit requirements. The outer Vextremity. 20 .of said tube 14 isdrawn into conform to the corresponding end of .the inner tube 6 so that the opening in that end of said tube14 is of 4substantially the same diameter as the bore of said tube 6.

The outer tube 5 is provided with a port 2 1 adapted to be connected in 'a suitable manner with a receptacle .(not shown) containing ,the spraying fluid or liquid fertilizer. When in use for .either spraying or npplyiu the liquid fertilizer, the tube 14 is adjus so as `to leave an opening between its inner end and the shoulder l5. The ring valve is adjusted so as to admit Water under pressure into .the tubular extension 4. The;

draw the spraying fluid or iguid fertilizer into the nozzle where it will become mixed with the water at the point of discharge and themixture delivered upon trees, shrubbery or lawns, as may be desired. It will be understoodthat the strength of the mixture may be regulated by adjusting the tube 14 to decrease or increase the size of the o ening between its inner end and the shou der 15. When the inner end of said tube 14 is engaged with said shoulder, the flow of the spraying iiuid o rliquid fertilizer will be cut ofi" entirely and pure water discharged through the nozzle. 'By'means of this adjustment the nozzle may be used for ordinary lsprinkling or watering urposes when desired, no connection with t e port 21 being necessaryv at such times. It will be further observed that the flow of the spraying fluid or liquid fertilizer and the water may be cut olf simultaneously by means 'ef the valve-ring.
